I found this animation being difficult to me. the small ball is moving straight, push the leg to swing. I tried many ways, but it doesn’t work. I sincerely hope you can give me some hints. Thank U!
Unfortunately Bongo has no collision detection. But some clever geometry (luckily you used a circle not an irregular curve) and our brilliant IK lend a helping hand.

When it’s somewhat over your head, let me know.
